E-bikes for steep roads: Mid drive and hub drive motor efficiency comparison
(Inderscience Enterprises Ltd., 2018-01-01)
Power input, speed, and efficiency concern people when selecting a transportation means. This study compares multiple e-bikes configurations and presents to the reader scientific criteria to choose the one that fits best ...
Driving AC motors through a long cable: The inverter switching strategy
(Ieee-inst Electrical Electronics Engineers IncNew YorkEUA, 1999)
Polyphase drive systems configuration aiming EMI mitigation
(Bilbao, 2014-03-26)
Topologies of motor drive systems are studied,
aiming the reduction of common-mode (CM) currents. Initially,
the aspects concerning the CM currents circulation are analysed.
The reason of common-mode voltages generation, ...
Speed Neuro-fuzzy Estimator Applied To Sensorless Induction Motor Control
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
This work proposes the development of an Adaptive Neuro-fuzzy Inference System (ANFIS) estimator applied to speed control in a three-phase induction motor sensorless drive. Usually, ANFIS is used to replace the traditional ...
